Ms Rimmer was one of three women who fell victim to the
Claremont serial killer in 1996 and 1997.

The VHS CCTV footage released today shows a brief interaction
between Ms Rimmer and an unidentified man, who police hope to
identify.

The rotating camera shows Ms Rimmer waiting near a pole outside the
popular nightspot. She acknowledges the man, before the camera pans
away.

When it returns, she is gone.

Detective Superintendent Jeff Byleveld from the major crime
division also revealed information about the killer's other victims
- Sarah Spiers and Ciara Glennon - during a police briefing
today.

The bodies of Ms Rimmer and Ms Glennon were found in bushland on
Perth's outskirts shortly after they went missing, but Ms Spiers
has never been found.

Superintendent Byleveld said it was difficult to tell if Ms Rimmer
was acquainted with the man seen in the video that was released
today.

More than 700 people were shown the footage at the time and have
been identified.

"We want to close that line of inquiry," Superintendent Byleveld
said.

He said there were sightings of the third victim, Ciara Glennon, on
Stirling Highway before she disappeared on Saturday March 15,
1997.

Witnesses described seeing Ms Glennon talking to the occupant or
occupants of a vehicle that stopped on the highway.

"The only certainty is that the vehicle was light-coloured and the
make and model can't be confirmed from witness accounts,"
Superintendent Byleveld said.

Ms Glennon was seen leaning over with her hands on her knees by
witnesses. They said when they looked back, the car and her were
both gone.

"There are other possible sightings of Ciara further along Stirling
Highway, so it can't be confirmed if she did, or did not, get into
this vehicle."

Ms Spiers had called a taxi on January 27, 1996 after 2am, when she
left Club Bayview.

A witness reported seeing headlights nearby on Stirling Road, where
Ms Spiers was reportedly waiting for the taxi. But the witness had
lost sight of the headlights after turning onto Stirling Highway,
Superintendent Byleveld said.

The Macro taskforce at the centre Australia's longest and most
expensive murder investigation was the most scrutinised of any
investigation team, Superintendent Byleveld said.

Investigators today defended their decision not to release the
12-year-old footage.

"They stood by that decision - they still do," Superintendent
Byleveld said.

A cold case review of the three murders had made no recommendation
on whether or not the footage should have been released.

The original footage was "underwhelming" and the enhanced footage
distorted height and colour, Superintendent Byleveld said.

He said investigators did not want to risk narrowing the focus of
the investigation by releasing the grainy footage at the time, in a
town where one whisper could change public perceptions.

The new footage was first released to a pay TV documentary series,
which enhanced the original material, but not to the general
media.

Superintendent Byleveld said police had used the pay TV documentary
as a vehicle for national coverage and hoped the coverage could
help them solve the mystery of the Claremont serial killings.

"That's what we hold in our heart - that we can do that,"
Superintendent Byleveld said.
